Final answer:
The original value of the baseball card is $0.25, determined by the equation 60v = 15, where v represents the original value of the card.
Step-by-step explanation:
To find the original value of the baseball card, we need to set up an equation based on the information provided. The current value of the card is 60 times its original value v. Given that the current value is $15, we can write the equation as:
60v = 15
To solve for v, divide both sides of the equation by 60:
v = 15 / 60
v = 0.25
Therefore, the original value of the baseball card is $0.25.
